ASoC: wm_adsp: Add CCM_CORE_RESET to Halo start core 



When starting the Halo core it is advised to also write the core reset
bit, this ensures the part starts up in the appropriate state.  Omitting
this doesn't cause issues on most parts but cs40l25 requires it and
it is advised on all Halo parts.
